It might be better as a monograph. I have tried to make the paper as modular as possible, isolating the computer-aided parts into clearly-defined units", "categories": [ "math.DS" ], "abstract": "In this long paper we give a fairly complete analysis of outer billiards on the Penrose kite. Our analysis reveals that this 2-dimensional non-compact system has a 3-dimensional compactification, a certain polyhedron exchange map, and that this compactification has a renormalization scheme. These two features allow us to make some sharp statements concerning the distribution, large-scale geometry, fine-scale geometry, and hidden algebraic symmetries of the orbits. For instance, one of our results is that the union of the unbounded orbits has Hausdorff dimension 1. We give a computer-aided proof of the results concerning the compactification and the renormalization. This proof involves finitely many calculations done with exact integer arithmetic.", "revisions": [ { "version": "v1", "updated": "2011-02-22T22:35:48.000Z" } ], "analyses": { "keywords": [ "penrose kite", "outer billiards", "compactification", "renormalizaiton", "polyhedron exchange map" ], "tags": [ "monograph" ], "note": { "typesetting": "TeX", "pages": 142, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1102.4635S" } } }
